TDS-1002b Any good? Comments?

really, well we all like them here, the tek's are being slowly replaced with lecroys, maybe we just have good lecroy salemen

the older, heavy, probeless, mono "burned" screen, non usb (RS-232) scopes don't hold their value too long, regardless of raw performance, people like lightweight, color scopes with high modern connectivity

Yup! Many a thread has raged over the lack of "user friendliness" in the Lecroys. But like anything, you get used to them.

Very true. But to get that raw performance in a new scope you have to spend at least 5 times that amount. So great value for those after the best performance-per-buck.

The sample rate is high though 500Msa/s, but I was most impressed by the protocol analysis/decoding. Oh well, I find that others can do the same thing.

The salesman from the other company just called and he doesn't have one in stock either. He does have the DS1101CD with the 16 channel logic analyzer.....hmm. That one captures at 200Msa/s with a 512K buffer, much much deeper, but it costs $500 more. Hopefully the PC software will be able to do protocol analysis/decoding. He's going to call me back with info on shipping and maybe even a discounted price.

I pretty much read the whole user manual. It certainly has features that I've wanted in the past. Just being able to see what happened before the trigger will be a boon. I doubt I really "need" this scope, but I sure do want it.

Of course not. You can just imagine how fast a bunch of engineers are filling it up for me. ;-)

As a general comment, I'm genuinely puzzled at the large number of people who need and seemingly make regular of, the pre trigger and pre storage facilities of digital scopes. Can't remember the last time I needed the facility. Am I missing out here, or doing something wrong, or thick or summat, or what?. john

Read my thread TDS 1012.

If it has anything in common, it's a HUMUNGOUS PIECE OF CRAP ! To call it a fetid turd would be KIND to it !

I have never before had so many hours of my very precious time wasted by an utterly useless piece of shit masquarading as 'test equipment'.

Graham

AaaarrgghhhH!!!!

Yes, I also have a TDS210 here too in connection with the same project as that TDS1012 I mentioned elsewhere.

Do I need to elaborate ? What Joerg says, I concur with. It's a heap of utterly unmitigated fetid steaming pooh.

It has to be said it wasn't *quite* as bad as the TDS1012. Damded with faint praise ? Yes, you got it !

Buy an decent analogue scope. There's no beating them. S/h analogue Teks are cheap on ebay and they will eventually run out. They'll never 'wear out' most likely though, at least not in your lifetime.

A 465 is tricky to beat but a 2465 does it !

Graham

that

the

do

It sure does. The 2465 is what I usually recommend to clients. Then they get them on EBay or through other places. Best scopes Tek ever made IMHO. With those new little bread-box thingies I have the impression they are just some kind of outsourced design. Like what HP used to do with Yokogawa designs, except that the results, well, ...

The only downside with the 2465 series is that they are only available used. And since they are some of the best scopes since sliced bread that means used a lot. So all the encoder shafts are usually sloshing around or like what happened to us you pull into delayed-trigger and hear plastic pieces rain down behind the front panel, meaning it won't switch back to non-delayed. Anyhow, it's best to budget in some serious mechanical fixing. The knobs, shafts and so on are IMHO a bit on the flimsy side.

You're NOT KIDDING !

I'd settle for a plain vanilla no-nonsense 465B. 2465s are lovely of course.

Graham

Since when did the probe need to near to the screen ?

Graham

In one's dreams these days apparently !

It wasn't a Coutant supply was it ?

Graham

Nice if you don't mind 1.5V of induced 48kHz !

Graham

Compare with CEOs prior to MBAs.

Graham

You're not an analogue man at heart are you ?

Graham

I meant "cannot shield". The old stuff is generally quiet. I prefer older equipment because it won't have switchers and the like. In my lab here about the only thing that is noisy is the computer so it needs to be off at times. Well, and our Rottie who sometimes comes in for a while because he snores.

No, it was HP. The good stuff.

Interesting. It just came to me: All of the potential clients that have decided to use my services and thus became clients are under the CEO leadership of an engineer, a scientist or at least a technical-minded person. And for some reason they regularly blow the competition out of the water.

HP have indeed done good stuff but not IMHO as good as Tek's until I came across

AAARRGGGHHHHHHH ! KILL KILL KILL !

You know what I'd like to do ?

I'd like to get a really nice AXE. Also a decent 'stone' on which to polish its' edge.

I would spend some time putting a very fine edge on the AXE until it could cut my own flesh and draw blood with a mere graze.

I would them place the TDS on a solid oak bench and chop the living daylights out of it with a thousand cuts !

That would not satisfy me however.

I would make sure I had a decent pair of Doc Marten's boots with steel toe-caps and additional hobnails.

The chopped-up remains of the TDS I would sweep onto the floor and then stamp on up and down for at least 5 minutes !

I would then collect the remains and transfer them to a quartz vessel where I would mix them with aqua regia.

Once so dissolved I'd neutralise the mix and incrporate it into a load of cement. The cement I would cast into a block and then when solid would knock to pieces with a ball on a chain.

The pieces I would collect and feed into a rock crusher.

I would finally drop the crushed rock from a helicopter into an active volcano.

And I'd still be cross !
